    9109-22 - 4-segment, redundant FISCO power supply system INM9109-1D August 2010 Figure 1 .1 9109-22 power supply assembly OVERVIEW The 9109-22 power supply system provides an intrinsically safe field network for F ™ oundation fieldbus systems in hazardous areas. It is intended for use with control systems equipped with H1 interface cards that must draw current from the host fieldbus segment in order to operate.

  • Page 7: Module Carrier

    2 .2 Module carrier The module carrier provides fieldbus power for four fieldbus segments. It supports pluggable power supply and arbitration modules for each segment and all connection facilities. Each carrier has pluggable screw terminal connections for redundant 24V input power and for the intrinsically safe field trunks.

  • Page 9: Surface Mounting

    Note: Because of the slotted mounting holes, 15mm of free space is required above the top edge of the assembly to allow the backplate to be mounted and demounted. 3 .3 .1 Outdoor mounting If the assembly is to be mounted in an outdoor location, a suitable enclosure with a minimum of IP54 ingress protection is required.

    3 .5 .2 Removing 9122-IS-CM power supply and SAM modules The FISCO power supply module must be removed before its associated SAM module. 1. Loosen the two securing screws of the FISCO power supply module and remove it. 2. Slide the red interlock tab on the SAM module to the side to obtain access to the securing screw head.

    method of mounting then a separate connection must be made from the ground terminal provided on the backplate to the enclosure’s protective ground. 4 .2 Alarm Connections Each SAM module and each HOST PSU module contains a solid state switch that is ‘closed’ in normal operation and in this condition exhibits a nominal resistance (@25°C) of 36W.

  • Page 12: Host System Connections

    Note: It is important during installation to segregate intrinsically safe wiring from other non- IS wiring and to mark it clearly as intrinsically safe. Two ground studs (IS Shield A and IS Shield B ) are provided on the module carrier, adjacent to the hazardous area field wiring connections.

  • Page 13: Testing And Fault Finding

    With this arrangement, the fieldbus instruments on both FISCO trunks appear logically on the same host H1 segment. For example with 6 instruments on each of the two IS field trunks, 12 instruments appear on the ‘live-list’ of the host H1 card. This can have the benefit of maximising the logical capacity of the host H1 card, and reducing the number of cards required for a given I/O count.

  • Page 14: Fault Finding

    Note: The default startup configuration always makes the ‘A’ power supply active. To confirm the Failover action of a redundant pair - with the ‘A’ power supply active: 1. Verify the power supply is not running a live process. Follow local plant procedures 2.

  • Page 15: Replacing Failed Modules

    5 .4 Replacing failed modules Because the 9109-22 is not installed in a hazardous area, any of the modules fitted to the carrier may be ‘hot-swapped’ i.e. replaced without isolating or disconnecting any incoming power supplies. If any module failure has been identified using, for example, the fault-finding procedures described in Section 5.3, follow the instructions provided in Section 3.5 to remove and replace the module.
